Question

Botulin is a poison with a molecular structure so similar to acetylcholine (ACh) that it blocks the effects of ACh in synapses, making botulin which kind of molecule?

A. endorphin
B. antagonist
C. autonomic
D. endocrine
E. agonist

Answer 1

Botulinum toxin (Botox) is a neurotoxic protein produced by Clostridium botulinum. It acts as an antagonist to acetylcholine (ACh) in synapses, blocking its effects and causing muscle relaxation and paralysis.

Step-by-step explanation:

Botulinum toxin (Botox) is a neurotoxic protein produced by the bacterium Clostridium botulinum. It has a molecular structure similar to acetylcholine (ACh) and acts as an antagonist to ACh in synapses. This means that it blocks the effects of ACh in synapses by preventing its release from axon endings at the neuromuscular junction, causing muscle relaxation and paralysis.
